Updated todo.md and nojs.njk

Added another todo entry.

Added required attribute to input file in No-JS uploader. This should
prevent submission when clicking Upload button before selecting any
files.

Removed built-in "safe" filter from some fields in nojs.njk, cause they
were unnecessary.

 * [ ] Add a copy all links to clipboard when there are more than 2 uploads in history.

+* [ ] I forsaked all `Promise.all()` in favor of `await-in-for-loop` a while back. I personally think it was fine, considering a lot of them were tasks that required serial processing (continuation be dependant on previous iterations), but maybe I should review the current codes to find any sections that would do just fine, or maybe even great, with `Promise.all()`.
